To ALL WHoM IT MAY ooNoER'N:

I Be it known that I, JOHN V. QTEPsoN, of the city of Brooklyn, in thecounty of Kings, and vState of New York, have invented certain new anduseful improvementsin Pipe Gutters, with wrench attachment; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference, being had to the annexed-drawing, making part ofthis specification, in which- Figure 1V is a side elevation of saidimproved wrench when fitted to screw or twist a piece of pipe. Figure 2is a side elevation of said wrench when fitted to cnt o a piece of pipeorcut out a transverse section of a line of pipe,`as the case mayrequire. i

Figures 3, 4, 5, 6, 7, and 8 are parts of the wrench tobe hereinafterreferredto.

In the drawing, A represents the head of the'wrench, in'the upper jaw ofwhich a slidingI or adjustable block, E, is inserted. This block shouldbe provided with lianges, `z a, to lap over on thexsides of the jaw, andshould be accurately tted in its place, and at the same time besusceptible of ready adjustment. This adjustable block'iis fitted with a.knife or cntter,.:l", as shown in figs. 4 and 6, and is moved forwardby means ofa screw-cut on the end of theV handle, C, which screw passesthrough the top of `the head, as shown in the drawing. `In thelower jawof the head thereis inserted a. knife or cutter D, made as shown inligs. and `5. This. .cutter is accurately tted in its place, and is heldin positiouby means of a tail-piece, which passes through `the 'lowerpart ,of the jaw, as shown byr. These knives or cuttersI prefer to makeVshaped on their cuttingv edge, so as to `make them bear in fourplacesupon the ,surface of a cylindrical pipe. 4

INOW, when this wrench is thus fitted to cut pipe Vwithfit is operatedby simply hooking it over theline of pipe, by then'screwing the handledown to bring the knives to bear against thepipc, and by `ther; movingthe handle lto and fro, by which the wrench is made to vibrate aroundthe pipe as a centre, the block, b eing moved forward' by the screw asthe knives cut their way into thepip'e'until itis cut olf. By this makeof wrench it will be seen a pipe fitter can cut a section or piece outof ai line'of pipe whe'nit lis so` situated that thewrench cannot be.turned or'rotated all. the way around the pipe; and the objectof makingthe cutters V-shaped isto enable me toicutall the way around the pipewith Aas little motion of the wrench as possible. New, when the wrenchistitted to screw `or twist'a pipe, the bloek, E with' its cutter F, andthe cutter`D,fa1-e taken out of the jaws andablock" :BV-made, as shownvby figs. Tand 8, is Apnt inthe place of the block E. Thisv blockhBshould be made with flanges and as accurately fitted in its place as theAblock E, and should'be runde with a'semifcircular bearing-place, .6, inits rear end-to support the endvof thelscrewG, when screwed `against thetail of the pawl,

C, fitted vin the block B upon a centre pin, in the manner.shown.` Thispawl, C, should be made `of steel, and

should be so shaped as to make the front end take hold of the pipe, T,lwhen the end of the screw is forcedagainst its rear end, `as shown. ,li l VThe drawing indicates so plainly the method of applying the wrenchto the pipe that no further description is thought necessary. i

Having now described the nature. and extent of 'my invention, I claimand desire-'to secure by Letters.;

Patent- Y v i The combination-of the stationary knife'D with theadjustable knife F, and the jaw A of'the wrench, coristructed and'arranged substantiallylas described. 4 l i i j 4 JOHN V. JEPSON.` Witnesses:
